CAN- COVER LOCK.

Original application filed March 9, 1918, Serial No. 221,421; Divided and this application filed January 12, 1920; Serial No. 350,961.

To aZZw/zom it may concern:

Be it known that I, GUSTAV LinsiiEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Can-Cover Lock; and I do hereby declare that the followingis a full, clear, and exact description of thesaine, reference being had to the accompanying drawings, and to the.

an improved frictional locking inechanisnr for a container and the cover thereof.

Another object of the invention'is to construct an oil can with a removable spout cap adapted to be locked in position against accidental removal.

It is an important object of this invention to construct a can body and its cover with frictional members which are adapted to be held. in frictional engagement against accidental release by means of locking members forming a part of certain of'the frictional members.

Other and further important objects of his invention will be apparent from-the disclosures in the specification and drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

011 the drawings:

Figure l is a side elevation of a can body and cover equipped with a cover locking mechanism embodying the principles of this invention.

Figure 2 is an enlarged bottom plan view of the can cover removed from the can.

Figure 3 is an enlarged fragmentary top plan view of the can body with the cover removed.

Figure 4 is a side view thereof.

Figure 5 is an enlarged detail section taken on line- 5-5, of Figure 1.

As shown on the drawings: j The reference numeral 1, indicates a can body, the upper end of which is rounded. to connect with, an Integral neck or collar 2.

The upper margin ofthe neck 2, is bent out- 'wardly at right angles to form a flange 3, having integrally formed on opposite, sides thereof, by cutting away portions of the flange, curved or are shaped ears or lugs 4'. One end of each of the ears 4,. 1s disposed in the plane of the flange 3', and has the end margin of one end thereof curled or bent downwardly to form a hook 5. The other end. of each of the ears 4:, is depressed or deilected downwardly as denoted by the reference numeral 6. The ears i, are disposed with the like ends thereof positioned dia-s rigidly secured by soldering or other suitable means, a passaged outwardly tapering spout or nozzle 8. integrally formed on the lower end of the casing 7, 1s a top or cover plate 9, the margin of which is bent downwardly to form a rim 10. integrally formed on the rim 10, are a pair of inwardly directed oppositely disposed earsor lugs 11, one end of each of which is bent or deflected outwardly, as de noted by the reference numeral 12. The ends of the ears 11, are arranged with the like ends thereof disposed diametrically opposite one another, as shown in Figure 2. Removably seated within the rim 10, of the cover and held in place by the ears 11, is a washer or packing ring 13, made of rubber, felt or any other suitable material.

An oil ejecting mechanism 14, is mounted within the can cover, and is adapted to be operated by an actuating lever 15.

The operation is as follows: 3

To close the can 1, the cover is placed upon the flange 3, with the cover plate ears 11, registering with the cut-out portions of the flange 3. lVith the parts in this position the downward bent ends 12 of ears or lugs 11 will lie adjacent to the hooks 5 of the ears or lugs 4L, and there will be sufiicient clearance between the two to permit said ends 12 to pass beneath said hooks 5 when the cover is rotated clockwise. Such rotation will cause the ears or lugs 11 to ride beneath the hooks 5, said ears springing downward until their other ends pass said hooks 5, which will occur when a quarter turn has been given, whereupon the free ends of lugs 11 will look behind said hooks 5. In this position reverse rotation is prevented, while further rotation clockwise will be resisted suihciently efiectually to prevent accidental rela tive movement of the parts, though with i sufiicient force applied this resistance may be overcome and the parts again unlocked by a further quarter turn.

With the cover locked upon the can body 1, a liquid such as oil within the can may be ejected by force through the spout 8, by first inverting the oil-can and then operating the lever 15, to cause the ejecting mechanism 14:, to trap oil in the casing 7, and then force the trapped oil out of the mouth of the spout 8, independently of any flexing of the sides or bottom of the can body 1.

I am aware that numerous details of construction may be varied through a wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a can body and the cover thereof, of frictional members integrally formed on said can body and cover and adapted to engage when the parts are rotated relatively, and hooks formed on one of said sets of frictional members adapted to engage behind the frictional members of the other set to lock the parts against reverse rotation. r

2. A can, comprising a can body, ears integrally formed thereon each depressed at one 7 end and formed with a hook at its other end, a can cover, and ears integrally formed thereon each depressed at one end, said cover .ears adapted frictionally to engage said can body ears and to look behind the hooks on said latter ears when the parts are rotated relatively.

In testimony whereof I have hereunto sub scribed my name in the presence of two subscribing witnesses.
